Russia recently confirmed its plans to purchase the Ukrainian-designed Antonov An-70 transport aircraft, as long as the company fixes several problems pointed out by Russian military officials.

The An-70 is a revolutionary aircraft. It is the first large aircraft to be powered by propfan engines. First flown in 1994, only two prototypes have been built, and both crashed in test flights. The An-70 has been in development for about 30 years.
